The abbreviation PMI stands for "Product and Manufacturing Information" and means functional dimensioning on a 3D CAD model. The idea of PMI is to cover the entire process chain from specification (CAD), through manufacturing (CAM) to verification (CAQ) with one data set containing all necessary information. In the long term, the technical drawing would become irrelevant and the derivation of the drawing would become null and void.
In dimensional metrology, this data set is to be used to generate a measurement sequence based on functional measurements on the 3D model. With the help of CALYPSO it is possible to import these CAD data sets in order to automatically generate a measuring program.
